We have a lot more snow this year than we have in the recent past. As you can see, the snow level is quite a ways up the chicken coop. We can open the door, and do most days. We only keep it closed when it's sub zero or the wind chills are extreme. Even with the door open though, the chickens don't like to come out. I can't say that I blame them. If I had a choice I don't think I'd go out in the snow either.
